JAMES .PATON, OF' CLEVELAND, OHIO; JOHN PATON AND JOSEPH C. SPARROW EXECUTORS OF SAID JAMES PATON, DECEASED.

SAFE OR VAULT.

SPECIFICATION forming part of Letters Patent No 769,323, dated September 6, 1904. Application filed September 26, 1903. Serial Noll'Mfl Ll. (Nomodel-l To (all whom it may concern.-

Be it known that I, JAMES PATON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,

' have invented certain new and useful Improve- 7 ing mechanism and of releasing the same and improved means of attaching the female screw- I ring to the body of the safe or vault and the male screw-ring to the safe or vault door.

My invention is shown in the drawings accompanying and forming a part of this specification, in which Figure 1 is a front elevation of a safe or vault, showing the door closed and a portion of the front plate of the door removed. Fig. 2 is a view showing the interior of the safe or vault shown in Fig. 1, showing a part of the inner plate of the door removed. Fig. 3 is a sectional view of the safe and part of the door upon the line as w of Fig. 2. Fig. 4 is an enlargedsectional view of a part of the safe door and body, showing the mechanism for releasing the locking-bolts. 'Fig. 5, is an enlarged side view of a part of the female screw-ring, showing the means employed for automatically raising the catch holding the locking-bolts. Fig. 6 is an enlarged side view of the outer ring of the door, showing the plate employed to hold the door when opened. Fig. 7 is a side view of the female screw-ring.

Like figures refer to corresponding parts in the several views. I

In the drawings, numeral 1 represents the body of the safe or vault, which may be constructed of any suitable form and of any suit able material, but preferably of a tough hard unmachinable metal, such as manganese steel. The body of the safe or vault is provided with a round door-opening, and fitting into this opening is a door 2, the body or main portion of which is preferably made of a similar hard tough metal. Fitting into the hard body of the safe is a ring 3, preferably made of a softer metal and having a female screw-thread, which in the drawings is shown as mutilated. The ring 3 is embedded in the body of the safe by the metal of said safe-body being cast around said ring and is provided with a groove or depression 4 in its outer periphery and a series of openings 5, which extend below the depression in the ring.

When the safe-body is cast, the melted metal of the safe-body flows into the depression 1 and openings 5 and completely fills the same, and when the cast metal becomes cold the engagement of the hard metal of the safe-body with the depression a in the ring 3 will prevent the ring from being driven out of its position, and the contact of the hard metal of the safe-body with the openings 5 will prevent the ring from being turned while embedded in the safe-body.

Fitting into the hard body 2 of the door is .a ring 6, preferably of softer metal and having a male screw-thread adapted to engage the female screw-thread in the ring A. A part of' the ring 6 may be embedded in the body of the safe-door bythe metal of said safedoorbeing cast around a part of said ring. It has been found that when the ring is cast into the door the metal of the door as it becomes cold may recede from the metal of the ring and leave the ring loose in the doorbody. To prevent this, 1 cause the ring to be provided with a series of openings 7, extending through that portion of the ring which engages the body of the door,'so that when the ring is cast into the door the melted metal runs through the openings 7 and causes the ring to be firmly held in the body of the door.

That portion of the ring 6 which engages the door-body is also preferably dovetailed, as

place by pins.10, screwed into the plate 8. Supported by the plates 8 and 9 is'a disk 11, which is connected with locking-bolts by means of crank-levers 13. Byapartial revolution of the disk 11 the locking-bolts 12 are shot in bolt-openings in the male screw-ring into corresponding bolt-openings in the female screw-ring. The disk 11 is actuated by a suitable automatic device connected with a pin 14, but not shown in the drawings.

Where a device is used for automatically throwing the locking-bolts in locking the door, it is necessary to have means for holding back the locking-bolts until the door is fully closed and then releasing the bolts. For this purpose I provide a sliding bolt 15, which fits in an opening in the .male screw-ring 6, as shown in Figs. 3 and 4. At its outer end the bolt 15 is provided with a head or arm 16, which has a beveled inner surface, as shown in Fig. 5, and projects out a sufficient distance to engage a corresponding beveled head 17, attached to the female screw-ring, as shown in Fig. 5. The bolt 15 is held in the opening in the ring by a plate 18 and'is provided with a head 19 at its inner end and is adapted to engage a slot 20 in the locking-bolt 12, as shown in Figs. 3 and 4.

Interposed between the head 19 of the bolt and the plate 18 is a spring 21, which causes the bolt 15 to be at all times in contact with the locking-bolt 12. hen the safe is unlocked, the head of the sliding bolt 15 engages the slot 20 in the locking-bolt and holds the bolt until the sliding bolt is withdrawn. As shown in the drawings, the male and female screw-rings have mutilatedscrew-threads, and when the door is closed the same is turned to bring the male and female screw-threads into engagement. The turning of the door for this purpose brings the beveled head 16 of the sliding bolt into contact with the beveled head 17, attached to the female screw-ring, which results in the withdrawal of the sliding bolt 15 from contact with the slot 20' of the locking-bolt 12 and the consequent release of the locking-bolts, which then are thrown into the bolt-openings in the female screw-ring by the action of the automatic device connected with the pin 14.

In the drawings the body of the door is supported by a crane-hinge 22, attached to the body of the safe in any suitable manner and which supports rollers 23, which engage an outer ring 24 of the door.

While in the drawings the screw-rings 4 and 6 are shown as having mutilated screwthreads, the rings may be made with continuous screw-threads, or interlocking lugs may be substituted for screw-threads, for the purpose of drawing the door into close engagement with the jamb of the door. Where any of these means of drawing in the door are employed, it is necessary that the door while open shall be held in such a position that the screw-threads or interlocking lugs will at once engage each other when the door is pushed into the jamb. To accomplish this purpose, a fixed pin 25 is attached to the crane-hinge 22 in a suitable manner and in a position to engage a stop 26, located on the side of the outer ring 24 of the door. The stop 26 consists of an upper arm 27 and a lower shorter arm 28, so disposed as to leave a space between the same sufiicient to allow the entrance of the pin 25, as shown in Fig. 6. When the door is drawn outwardly in opening, the outward movement of the door causes the pin 25 to pass from the point shown by the dotted lines at 29 in Fig. 6 to the point between the two arms of stop 26, as shown in Fig. 6, and prevents the door from being further revolved and retains it in proper posi tion to again enter the door-jamb. \Vhen the door is pushed toward the door-jamb, the pin 25 recedes from its position of engagement with the arms of stop 26 to the position shown by the dotted lines at 29 in Fig. 6, thus leaving the door free to be screwed into the doorjamb.

The Words unmachinable metal as employed herein relate to metal of that character that it is not practicable to bore or cut the same with ordinary tools, but which can only be practically worked by grinding.

hat I claim, and desire to secure by Letters Patent, is

1. In combination, a safe or vault door of hard, unmachinable metal, and a male screwring having the part which engages the door dovetailed and provided with openings extending through the ring, the ring being embedded in the body of the door, by the metal of the door being cast around the ring and into the openings aforesaid.

2. In combination, a safe or vault door of hard umnachinable metal and a male screwring having the part which engages the door provided with openings which extend through the ring, the ring being embedded in the body of the door by the metal of the door being cast around the ring and into the openings aforesaid.

3. In combination, a safe or vaulthaving a body of tough, unmachinable metal, and a female screw-ring having around its outer periphery an annular channel, and openings ex tending into the ring from the channel, the ring being embedded in the body of the safe or vault, by the metal 'thereof being cast around the ring.

4. In combination, a safe or vault having a suitable door-opening, a suitable door, a hinge carrying the door, a fixed pin attached to the hinge, and adapted to engage a stop attached to the door and provided with a longer and a shorter arm so disposed as to engage the stop when the door is opened, and to release the door when closed, substantially as shown and described.

5. In combination, a safe or vault door of unmachinable metal, a male screw-ring a part of which is embedded in the body of the door machinable metal, a male screw-ring a part of.

which is embedded in the body of the door by the metal of the same being cast around the ring and having a female screw-thread, and

an outer plate supported by a detachable plate having a male screw-thread which engages the female screw-thread of the screw-ring substantially as described.

7 In combination, a safe or vault-body having a female screw-ring, a door provided with corresponding male screw-ring and lockingbolts adapted to enter bolt-openings in the female screw-ring; a sliding bolt held in the female screw-ring, its inner end adapted to engage and hold back one of the locking-bolts and its outer end being provided with a beveled head adapted to engage a beveled head attached to the female screw-ring and to cause the sliding bolt to withdraw from the lockingbolt when the door-is closed, substantially as described.

In testimony whereof I have signed my name i to this specification in the presence of two subscribing witnesses.
